I want to create a camera perspective where the character is centered in the screen (using the ScrollTo behavior) and always faces a certain direction (270 degress). As he turns and moves around (using the 8Direction behavior), the layer, itself rotates. In comparison this is very similar to Mode7 rotation on the Super Nintendo.

Does anyone have any suggestions?

The trick I'm having is how to isolate the difference between the angle of the character and the layer while maintaining a constant angle value of the character. My first attempt ended up rotating the entire layer so much that it looked like a kaleidoscope doped up on Red Bull.
